Long ago, there lived a man called Ramappa. He was very poor. He had a daughter by the name Rohini. Rohini was very beautiful and intelligent too. Ramappa had a cow. By selling its milk in the city he was earning money. As he has become old, Rohini herself was going to city to sell the milk. One day , Rohini was on her way to city to sell the milk. To reach the city, she has to pass the forest. That day also, she was walking carrying the milk. That time, a bear attacked her. She was very panic and shouted for help. King of that country was happened to pass that forest at that time. He listened and came for help. He succeeded in diverting the attention of bear . Soon he was able to rescue Rohini . Rohini invited the king to her house. King met Rohini's father. As king had started liking Rohini, without any hesitation he asked for the hand of Rohini with her father. But Ramappa was not ready to give his daughter to a stranger , as he was not aware that stranger himself is the king . Finally Ramappa said he will tell his decision in the night . When it was night , King was eagerly waiting for answer. That time Ramappa looked at sky and asked King to count the number of stars and to tell the answer by tomorrow morning ! King thought counting is not the big thing. He sat on a chair and started counting . But he was unable to keep the record. He thought sky is so vast and how will he ever be able to count the stars ?!! It was early in the morning . Rohini had started doing her daily work . By seeing King in great tension , she asked for reason . King explained his wish to marry her and the condition put by her father . Rohini stood thinking . That time she noticed a cat passing . She had an idea and asked King to do as she say. In the morning King went near Ramappa. Ramappa looked at his face. King was holding cat. Showing the cat to Ramappa , King said " there are as many stars on the sky as the number of hairs on body of this cat . If you want you can count by yourself ! ". Ramappa had come to know his daughter is behind of all these. Soon marriage took place .
